The PXA series Xscales used in PDAs were seriously crippled, a 200MHz ARM9 based unit could run rings around a 400MHz PXA265 on everything except pure cache bound arithmetic.

But then entire Xscale range suffered from an appalling bad memory system implementation as can been seen on the IOP series used in the Iyonix. And don't even get me started on the hideousness of the pipeline with all of the data hazards the XScale is blighted with, something ARM avoided in their implementations.

Intel are certainly no DEC, and should stick to rebodging PIIIs.
